This debut by Atlantic magazine senior editor Rosin bears witness to a paradigm shift currently turning the gender norms of American society upside down. "Plastic women," adaptable in a changing economy and culture, dominate institutions of higher education and steadily infiltrate the cubicles and boardrooms of a corporate America, and no longer need men to be the breadwinners. "Cardboard men," especially working-class and unskilled men, forced out of their factory jobs by the growing industrial flight, struggle to find purpose and employment in an evolving economy that values brains over brawn and the ability to build teams over handiness with a hammer. Rosin explores these changing gender norms across several settings, from the bedroom to the jail cell (more women are being arrested for violent crime than in the past), and teases out the highs and lows experienced by women attempting to shoulder the breadwinner and housekeeper roles simultaneously. Rosin's passion for the subject is married with the depth of understanding gained from years of reporting to produce confident prose and thorough citation. She deftly balances academic research with relatable anecdotes, from sorority sisters to single mothers. Rosin ends with a vision of both genders putting aside outdated traditions and finding a new normal built on the strength of human connection. (Sept.)
